You never appreciate what you have until it is gone sometimes. Some people never appreciate you even when you are gone. They are so self-serving and self-centered that anything that isn’t of direct and immediate benefit to them does not even appear on their radar. They are so in love with themselves that there is none left over for you. No matter how hard you try, no matter how flexible or understanding you are and no matter how much you love them, they will never ever change who they are. They will not magically wake up some day and fully appreciate what a wonderful person they are with.
